Teens sleep longer and perform better when school starts later

Teenagers naturally fall asleep later, which makes early school start times a recipe for chronic sleep deprivation. Researchers studying a Swiss high school that introduced flexible start times found that students overwhelmingly chose to begin later—and ended up sleeping about 45 minutes longer each school night. The extra rest led to fewer sleep problems, better well-being, and improved academic performance.

Archaeologists uncover brutal Iron Age massacre of women and children

A prehistoric mass grave in Serbia reveals that more than 77 people—mostly women and children—were deliberately killed in a brutal act of violence about 2,800 years ago. Genetic evidence suggests the victims came from different communities, indicating the massacre may have been a calculated message during fierce territorial struggles in Iron Age Europe.

Satellites are exposing weak bridges in America and around the world

Satellites are giving scientists a powerful new way to watch over the world’s bridges. Using radar imaging, researchers can detect millimeter-scale movements that may signal early structural problems long before inspectors notice them. The study found many bridges—especially in North America—are aging and increasingly vulnerable, but satellite monitoring could sharply reduce the number classified as high-risk. The approach could be especially valuable in regions where traditional monitoring barely exists.

Scientists warn fake research is spreading faster than real science

A sweeping new study from Northwestern University reveals that scientific fraud is no longer just the work of a few rogue researchers—it has evolved into a global, organized enterprise. By analyzing massive datasets of publications, retractions, and editorial records, researchers uncovered networks involving “paper mills,” brokers, and compromised journals that systematically produce and sell fake research, authorship slots, and citations.

Bird droppings helped build one of ancient Peru’s most powerful kingdoms

New research suggests seabird guano helped transform the Chincha Kingdom into one of the most prosperous societies in ancient Peru. Chemical clues in centuries-old maize show farmers fertilized their crops with guano gathered from nearby islands, dramatically boosting yields in the desert landscape. The resulting agricultural surplus fueled trade, population growth, and regional influence.

Tiny clump of moss helped solve a shocking cemetery crime

A tiny piece of moss helped expose a cemetery scandal in Illinois, where workers allegedly dug up graves and resold burial plots. By identifying the moss and analyzing its chlorophyll to estimate its age, scientists proved the remains had been moved recently—evidence that helped secure convictions.

2700-year-old teeth reveal the hidden lives of Iron Age Italians

Iron Age teeth from southern Italy have become time capsules, preserving intimate details of childhood and diet. Growth lines in the enamel reveal moments of early-life stress, while hardened plaque holds microscopic remains of cereals, legumes, and fermented foods. The findings suggest a community with diverse food resources and strong Mediterranean connections. Even a small sample offers a striking glimpse into how people lived, grew, and ate nearly three millennia ago.
